' Allis-Chalmers HD-14 tractor by Richard Campbell The Allis-Chalmers HD-14 was introduced in 1939 and was broadly based on that company’s earlier and very successful Model L and LO gasoline powered crawlers. At the time of its introduction, the HD-14 was the largest track type tractor that Allis-Chalmers had manufactured and joined two other machines, the HD-7 and HD-10, which Allis-Chalmers had also released that same year. Over 6400 HD-14 and HD14Cs were manufactured between 1939 and 1947 when the type was discontinued. '
